Is this how the determination was made that Archaeopteryx was
a flightless bird? I mean, if it's extinct, how do you really
know? I remember everything I used to see about Arch. said that
it was flightless; now I see a lot of depictions of it as a
flyer, or if not a flyer, at least a glider or hopper, rather
than being totally earthbound.
